Ease of navigation on a website is a very important part of design. If people visit a page on your site and then don't see a link back to the main page or other pages on your site then they are very likely to leave it completely. People hate to use the Back Button on their browser!

There are two very common ways of putting a Navigation Bar on your site. Side bars and top/bottom bars. I personally prefer a bar down the left hand side of the page and this has been proved to be easiest for people to use. Top or bottom navigation can also work very well, though, and lets you use the whole width of the page. They are especially good if people are reading through a long page and will reach the bottom and want to find another page.

There are two main ways of adding a navigation bar to your site. One is by using frames and the other is by using tables. Each has good and bad points.

Frames are very easy to update because you will only have to change one page if you add something to the navigation bar. They have two bad points, though. Some older browsers do not support frames so your will need to put a no-frames version of your site so that these people can view it. The other problem is that a lot of search engines will not spider (add) frames pages to their database.

Tables are completely the opposite of frames because if you update the navigation bar you will need to update every page on your site. Tables are more compatible than frames, though, because search engines understand them and more browsers support them.

For more information read the tutorial, Frames Vs. Tables. This tells you all the good and bad points of both frames and tables and how to create them.

Just remember that the user doesn't know what's on your site unless you tell them. Help them to find their way around and your site will be popular.
